Pulse audio (pavucontrol) sits on top of alsa so what you need to do is 
to use alsamixer first, select your audio card [use the F5 key to see 
all channels and F6 key for the audio card] then make sure that you have 
the appropriate channels selected (ie, unmuted and you mute/unmute them 
by using the "m" key).

While doing the playing around with the channels have what you want to 
hear playing so that when you unmute a channel you will hear the audio 
being played.

Just a note here: there are situations where having a combination of 2 
channels unmuted can actually prevent the audio from being heard - I 
don't remember what they may be but just be aware when you start 
fiddling with the channels; you will soon enough hit on the right setup.

Once you have sound thru alsamixer go back to pavucontrol and set that 
up to get your sound using pavucontrol.
